What Are App Permissions — And Which Ones Should You Allow?

Apps on your phone ask for permission to use your camera, location, and contacts. Here's what each permission means and how to decide.

What Is an App Permission?

When you install an app on your phone — whether it's a game, a weather app, or a recipe finder — it will often pop up a message asking your permission to use certain features of your phone. This might say something like: "Allow this app to access your location?" or "Allow this app to use your camera?"

These are called app permissions. Think of them like asking permission to borrow something. Your phone is asking you: "This app wants to borrow your camera — is that okay with you?"

The good news is that you are in charge. You can say yes, say no, or change your mind later. Nothing is permanent.ℹ️ Good to Know

Apps need your permission before they can access sensitive parts of your phone. This is a built-in safety feature — your phone won't let any app secretly access your camera, microphone, or location without asking you first.

Why Do Apps Ask for Permissions?

Sometimes the reason makes perfect sense. A maps app needs your location so it can show you where you are. A video calling app needs your camera and microphone so the other person can see and hear you. These are legitimate requests, and allowing them is perfectly fine.

But some apps ask for permissions they don't actually need for their purpose — and that's where it's worth pausing and thinking before you tap "Allow."⚠️ Watch Out

If a simple flashlight app asks for access to your contacts and microphone, that's a red flag. Ask yourself: does this app actually need this to do its job? If the answer is no, it's perfectly fine to say no — or delete the app entirely.

The Most Common Permissions — Plain English

Here's a plain-English guide to what each permission means and when it's reasonable to allow it:

PermissionWhat it meansWhen to allow
📍 Location The app can see where you are on a map. ✓ Allow for maps, weather, and restaurant apps. Ask for others — many apps request this just to sell your location data to advertisers.
📷 Camera The app can use your phone's camera to take photos or video. ✓ Allow for camera, video call, and QR scanner apps. Deny for apps where it makes no sense, like a news or shopping app.
🎙️ Microphone The app can listen through your phone's microphone. ✓ Allow for voice calling, Siri/Google Assistant, and video apps. Deny for apps with no obvious voice feature.
👥 Contacts The app can see all the names and phone numbers saved in your phone. ✓ Allow for calling apps and messaging apps like WhatsApp. Deny for games, shopping, and most other apps.
🖼️ Photos The app can view and access the photos stored on your phone. ✓ Allow for photo sharing, printing, and editing apps. Consider choosing "Selected photos only" rather than "All photos" when offered the option.
🔔 Notifications The app can send alerts and messages to your phone screen. Your choice. Allow for apps you actively use and want reminders from. Deny for apps that would just clutter your screen with ads.
🏃 Motion & Fitness The app can track steps, movement, and physical activity. ✓ Allow for fitness and health apps. Deny for all others — there's rarely a good reason for a recipe app to know how much you've walked.
📅 Calendar The app can view, add, or change events in your calendar. Be selective. Allow for scheduling apps. Deny for most others.

How to Check and Change Permissions on an iPhone

You can see exactly which apps have access to what on your iPhone — and change anything you're not comfortable with. You don't need to uninstall the app to take away a permission.

  1. 1Tap the Settings app on your home screen (it looks like a grey square with gears).
  2. 2Scroll down and tap on Privacy & Security.
  3. 3You'll see a list: Location Services, Contacts, Calendars, Photos, Camera, Microphone, and more. Tap any one of them.
  4. 4You'll see a list of every app that has asked for that permission, and whether you've allowed it. Tap any app to change its setting.💡 iPhone Tip

For location, you can often choose "While Using the App" instead of "Always." This means the app can only see your location when it's open on your screen — not quietly tracking you in the background all day.

How to Check and Change Permissions on an Android Phone

The steps are very similar on Android, though the exact wording may vary slightly depending on which phone you have.

  1. 1Tap the Settings app (the gear icon, usually in your app drawer or top menu).
  2. 2Scroll down and tap Privacy or Apps (depending on your phone, the option may be in a slightly different place).
  3. 3Tap Permission Manager. You'll see categories like Camera, Location, Microphone, and Contacts.
  4. 4Tap a category to see which apps have access, and tap any app to change its permission.💡 Android Tip

You can also go to Settings → Apps, tap a specific app, and then tap Permissions to see exactly what that one app is allowed to do.

The Golden Rule for Permissions

When you see a permission request pop up, ask yourself one simple question:

Does this app need this permission to do the thing I downloaded it for?

A flashlight app needs nothing except your flashlight. A recipe app needs nothing except the ability to show you a recipe. If an app asks for access to your microphone, contacts, or location and you can't think of a good reason why it would need those things — tap "Don't Allow."

The app will almost always still work fine. The permissions it's asking for often have nothing to do with what you actually downloaded it to do.


The Bottom Line

App permissions exist to protect you — and you are always in control. A simple rule: only allow a permission if the app clearly needs it to work. You can check and change any app's permissions in your phone's Settings at any time, and taking away a permission will rarely stop an app from working the way you expect it to.
